Now for my overall opinion... First of all, there's a slight scent while applying. It's so light that I hardly notice anymore and I'm towards the end of using this product. I just sniffed the product and it is light. It does have a slight scent of citrus. Secondly, I like the packaging. The packaging fits with the theme of their derma e Vitamin C Renewing Moisturizer. The only difference is I would finish derma e Vitamin C Renewing Moisturizer a lot faster than the serum. I will go into that in a little bit. It's well-made and sturdy. It's made out of thick plastic. The top is also sturdy. I can hear a clicking noise when I close the top. Also, I can feel a tight seal when I open and close. I cannot see it open or break unless you are rough with the packaging. For that reason, it's travel-friendly. It's also thin enough to hold with one hand. The pump is nice too. You have full control of the quantity you pump. This might sound weird but I like there's a slight see through in the back. The label does not wrap around the whole bottle. I like seeing my products go down. Third, the consistency is medium. It's not too liquidity that it runs everywhere. It's also not too thick that it's hard to work with. It's a good thickness serum. A little goes a long way with this product. Three pump covers my whole face and neck. Going back to the moisturizer, I use a lot more than the serum. It's more like two bottles of the moisturizer will equal one bottle of the serum. I don't know why companies do that like with shampoos and conditioners. You know what I mean right or am I the only weird one? It's probably the second. With that said, it's easy to use. It spreads easily and sinks into the skin quickly. It leaves a nice, smooth texture and not greasy at all. I honestly believe this product is the beginning step of the skincare routine. Without this product, the other products (eye cream and moisturizer) will not make a huge difference on the skin. You need to use all three in combination. Without all three, you only get the minimal effect. You want the maximum effect or at least starting in your early 20's. I noticed my skin looks more youthful and alert. I also noticed it's hydrated, more plump, and less noticeable fine/deep lines. Lastly, I'm glad I got to use this product. It's a good serum. It's not great but it's a great first step of the skincare routine for people in their 20's and 30's.
